No, Only 1 time choice of material for 1 calculation.
However,
1 material has, for example, 20 sizes having different properties, while that material has other properties (u, f, etc.) regardless of the sizes.
When I have only 1 list box, how can i skip (or JUMP!) the whole properties to stack other ones?
then do i have to duplicate the properties 10 times if there are 10 columns (having other properties) for each material? on_
